CLEANER FOR STEAM-BQILERS.

SPECIFICATION forming part of Letters Patent No. 244,668, dated duly 19, 1881.

' Application filed June 9, 1881. (No model.) I

-To all whom it may concern Be it known that I, CHaIs'r. REISER, a citizen of theUnited States, residing at Prairie d u Ohien, in the county of Crawford and State of Wisconsin, have invented certain new and useful Improvements in Cleaners for Steam-Boilers; and I do hereby'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,reference being had to theat-companying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. l

Figure 1 is a sectional view of this invention as in use in a steam-boiler. Fig.2 is a side elevation of the cleaner. Fig. 3 is-a transverse section of the cleaner, shown in Figs. 1 and 2. Thisinvention relates to that class of devices which are designed for use in steam-boilers to prevent the deposit of sediment or any impurity in the Water or the formation of scales; and the novelty consists in the peculiar structure of the present cleaner, whereby a cheap, 2 5 simple, and very efficient cleaner is produced, all as will now be more fully set out and explained.

In the accompanying drawings, A denotes any ordinary boiler, and B the cleaner placed 0 inside near-the top, and preferably mounted on the rests O, which are placed transversely on the upper row of the boiler-tubes a. The

water is introduced through the inlet-pipe 'D, to which the feed-pipe is attached. This pipe D is placed in the crown of the boiler centrally over the cleaner B, and is preferably -shaped. Thus the water flowing through this inlet will fall upon then pper, longitudinal shelf or trough E of the cleaner near the middle, and between the guards or flanges 6, so as not to splash over upon the shell or fines of the boiler and since E slopes downwardly at each end the water will readily find its way off the ends of E into the pans or traps F. The inner edges of these 4 5 pans at f are cut away slightly, so that when the water rises it will find its way over said edges down the inclined troughs G, which are under the trough E, and fall into the central pan or trap, H, in the lower trough, I." The sides overflow from thispan will go into this tr'ough I, and as the water rises hereinwill find its escape through the overflow -pipes K, which are placed near each end of the trough I, and depend down between the boiler-pipes as low as may be'desired. By this peculiarly-formed circuit or course for the water-flow the best opportunity is offered to catch and retain all impurities which may exist in the water, either in form of sediment or otherwise, and thus the water-finally finding its way into the boiler will be quite pure, and so nearly or wholly preventing the formation of scales inside the boiler.

All persons who use boilers know how great the need for some simple and complete device of this sort. From no other cause is more harm done to boilers than by the use of water impregnated with impurities. There is no shell or covering to inclose the cleaner, and it is thus fully exposed to the steam inside the boiler.

My present device is exceedingly simple in structure, and can be readilytaken apart and put in place through the man hole of the boiler, and in like manner as readily removed when it may be necessary to clean out the impurities or sediment which have collected in the many traps or pans it afl'ords.

Having thus described myinvention, what I consider new, and desire to secure by Letters Patent, isv 1. In combination, with the tubes a of a steam-boiler, the cleaner B, having central inlet, D, troughs E and G, traps or pans F and H, and pipes K, substantially in the manner and for the purposes set forth.

2. A steam-boiler cleaner composed of the following separable and detachable parts, namely: the lower pan or trough, I, having the overflow-pipes K at each end, and central trap, H, the inclined troughs Gr, traps F, and upper trough, E, with guards e and feed-pipe, all constructed and combined substantially as described.

In testimony whereof I affix my signature in presence of two'wit-nesses.

CHRIST. REISER.
